Glow in the Dark Letterbox Numbers

Introduction: Glow in the Dark Letterbox Numbers

Have you ever driven down a street looking for somebody's house but you can't see the numbers on the letterbox because it's too dark? You pull into random driveways to shine the headlights on letterboxes but there has got to be a better way. Well here it is!

Presenting "Glow in the dark letterbox numbers" inspired by my son's invention Glow in the Dark Seatbelt Buckle Band - (tintinmovie) With this invention, your visitors will never have to squint to see the numbers on your letterbox at night time ever again. Have fun with it.

Step 2: Making the Skin

Mix the glow in the dark powder with the silicone on the icecream container lid with the spatula. Spread it out evenly and you can press the surface down with damp fingers until it is smooth. Allow to dry for about two hours.

Carefully scrape the skin off the icecream container lid with the spatula. If the skin sticks to the spatula wipe it clean with a little turps or kerosene.

Step 5: Sticking on Numbers

As the skin will not be completely dry you should be able to stick it directly onto the letterbox. However I put a little silicone on the back to make sure that it is firmly glued to the surface. The silicone requires a fully 24 hours to cure before it will be water proof.
